There isn't anything specific to configure on the gateway. What interface type is the DTMF being sent over? Is this using DTMF relay? One possibility might be to insert a longer interdigit gap. What DTMF parameters were you using on the previous interconnect to this destination?

Paul, do you mean adding a timeout after each digit being sent? Thanks.

Yes, increasing the time between digits. The timer granularity is only 1 sec so you have to use a different approach to get sub-second gap. You could try a one sec gap though just to see if it works.

Enhanced version attached that allows you to specify the DTMF duration and interval.  It's quite a significant code change in the TCL to do this so you should ensure it's tested thoroughly before any serious deployment.

Paul,
The TCL works fine except that when dialing a DID, it skips the first digit to be sent. so if we are sending dtmf 1234, it sends 234. So to fix it we added an extra 0 at the begining to be removed later automatically. Now we need to dial ESN instead of DID and we see two digits are being skipped. Is there any way to find out why these digits are being skipped when sent out? Thanks.

Arvand,
 
I think you probably need to check your dial-peer configuration as the TCL has no control over how the destination number is signalled in the outgoing call setup; it merely requests the call setup and supplies the destination number for outgoing dial-peer matching.
 
Paul
